JOHN E. PARKER, OF BELOIT, WISCONSIN.

DRIVE-WELL POINT.

SPECIFICATION forming part of Letters Patent No. 313,882, dated March 17, 1885.

Application filed November 12, 1884. (No 'model.)

To all whom-it may concern:

Be it known that I, JOHN E. PARKER, of Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Drive-Well Points; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in drivewell points; and its objects are. first, to furnish a drive-well point consisting of one entire piece; second, to provide a drive-well point so constructed that when in position water may have free access to the interior thereof through lateral orifices. I consider malleable iron the most suitable material out of which to manufacture the herein-described drive-Well point.

Referring to the drawings, Figure 1 represents a view of one of my improved drive-well points before being covered with the customary wrappings of wire-cloth and perforated plate. Fig. 2 represents a longitudinal central vertical section of Fig. 1,t hrough the dotted line a: a: of Fig. 3. Fig. 3 represents a transverse sections of Fig. 1, through the dotted line 3 y. I

The acorn-shaped pointA will be sufficiently strong if cast hollow, as shown at A. The point is enlarged at A, in order that in descending into the earth it may-.make a hole of larger diameter than that of the shaft-like portion B, thereby usually saving the wrappings of the point from skinning by coming in contact with stones projecting from the sides of the hole. The columnar portion of the point consists exteriorly of a series of a1- ternating annular projections, O, and transverse grooves D, interiorly of the longitudinal grooves and strengthening ribs E F.

G G are rectangular openings extending from the exterior to the interior of the point through the grooves D. The annular projections 0 furnish supports for the Wrappings of wire-cloth and perforated plate, While the transverse grooves D afford free passage-ways for water flowing through the openings G into the reservoir H. The interior of the upper end, I, of the point is furnished with an internal screw, into which can be turned an external screw cuton the end of a water-pipe.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

As a new article of manufacture, the herein-described drive-well point havingthe acornshaped point A, enlarged at A the exterior annular projections, O,intermediate transverse grooves, D, thelatter provided with the openings G, the longitudinal groovesF, and longitudinal strengthening-ribs F, substantially as described.
